This article presents the significance of phsical simulation for studyinggeneral characteristic parameters of radio proximity fuze and analyses simulativeinitiating Conditions of the fuze in the process of missile-target encounter basedon the theory of simularity. Emphasis is put on the discussion of simulativeprogram to reduce the size of model target and the velocity, and on the analysis of the requirement for various simulated parts of fuze in simulation.

This paper deals with the charactetistics of the disturbed motion caused byseveral major disturbing factors about rocket-assisted projectiles, and gives cal-culating formulas derived for the dispersion and the ascertainment of reasonableigniting condition, which provides a means for choosing some important designparameters and analyzing the dispersion. The paper is divided into followingtopics: 1. The characteristics of the disturbed motion of field fin-rocket-assistedprojectiles; 2. The limiting values of deflection...

This paper deals with the charactetistics of the disturbed motion caused byseveral major disturbing factors about rocket-assisted projectiles, and gives cal-culating formulas derived for the dispersion and the ascertainment of reasonableigniting condition, which provides a means for choosing some important designparameters and analyzing the dispersion. The paper is divided into followingtopics: 1. The characteristics of the disturbed motion of field fin-rocket-assistedprojectiles; 2. The limiting values of deflection produced by the initial disturbances underthe condition of high-initial velocity; 3. The disturbed motion produced by the periodic disturbing factors under thecondition of high-initial velocity; 4. The determination of the reasonable igniting condition; 5. The dispersion of vertical target about rocket-assisted anti-tank projectiles.This paper is a revision and supplement of the author's paper [1].

In this paper the signal generated by the small coil target is analyzedand the cause for error produced in the measurement of muzzle velocity of a riflebullet with the small coil target is researched. The method how to raise theaccuracy of measurement is also discussed. The muzzle velocity of 7.62mm 56type rifle has been measured with the small coil target and a favourabledata has been obtained. It shows that the small coil target can give the higheraccuracy and will be available to verify...

In this paper the signal generated by the small coil target is analyzedand the cause for error produced in the measurement of muzzle velocity of a riflebullet with the small coil target is researched. The method how to raise theaccuracy of measurement is also discussed. The muzzle velocity of 7.62mm 56type rifle has been measured with the small coil target and a favourabledata has been obtained. It shows that the small coil target can give the higheraccuracy and will be available to verify the accuracies of measurements withother kinds of coil targets in the same conditions. In addition, the error that may occur when measuring the muzzle velocityby the Eletronic Counter Chronograph DCS-451 associated with the small coiltarget is analyzed in more detail and the farther treatments for improvementare presented The experiments show that they have reached the desired results.
